Probably get cold vote for this, but maybe worth it for those looking for a cheap SSD upgrade like I am.
I don't need the best IOP or transfer speed, but anything better than the 5400rpm drive in the Mac Mini I have.
This is £67.57 if you have Amazon Prime but not PrimeNow, but if you can get PrimeNow AND it is your first order, use the code 10OFF60 to get £10 off (somehow PrimeNow requires a tip of £2, so really £8 off).
I thought quite cheap for a 240gb SSD consider prices have shot up.
Hope this helps someone.
